I've got a Shuttle AK31v3 motherboard (KT266/A chipset) which does registered+ECC memory: System Mainboard Manufacturer : HOLCO (Shuttle) MP Support : No Model : VT8366-8233 BIOS ID : 04/17/2002-VT8366-8233-6A6LVH2CC-00 Chipset : VIA KT266/A Chipset [ ... ] Logical/Chipset Memory Banks Bank 0 Setting : 128MB DDR-SDRAM Registered 8-1-1-1R 4-1-1-1W 2.5-3-3CL 1CMD Bank 1 Setting : 128MB DDR-SDRAM Registered 8-1-1-1R 4-1-1-1W 2.5-3-3CL 1CMD Bank 2 Setting : 256MB DDR-SDRAM Registered 8-1-1-1R 4-1-1-1W 2.5-3-3CL 1CMD Speed : 2x 133MHz (266MHz data rate) Multiplier : 1/1x Memory Modules Memory Module 1 : Micron 18VDDT3272DG-265Z1 080EBD07 256MB 18x(16Mx8) ECC DDR-SDRAM PC2100R-2533-750 (CL2.5 upto 133MHz) (CL2 upto 100MHz) Memory Module 2 : Micron 9VDDT3272G-265B2 1B1B108E 256MB 9x(32Mx8) ECC DDR-SDRAM PC2100R-2533-750 (CL2.5 upto 133MHz) (CL2 upto 100MHz) ...but you and the other posters are right in pointing out the sad lack of ECC in newer AMD motherboards. Most of the other systems which use DDR SDRAM that I've tried this memory in (including a VIA EPIA/M and an Xserve) not only can't enable ECC or enable registered mode memory access, they won't even POST. -- -Chuck
